Why Are We Here?Why Are We Here?

• To measure the interest in forming an 802.3 Study Group to investigate:– The additional application of Ethernet to time sensitive

consumer Audio/Video Devices• Time and phase sensitive applications within a limited space• New networking requirements created by Digital Media

• Not to– Fully explore the problem– Debate strengths and weaknesses of solutions– Chose any one solution– Write a PAR and 5 Criteria– Write a standard or specification


4July 2004

Why now?Why now?

• This CFI has been in gestation for over a year– Bob Metcalfe challenged us last year to support new applications

Year 32

– Voice and video home entertainment will be networked– Pioneer and Gibson Labs attended the July 2003 Plenary– Off-line discussions ensued prior to November 2003 Plenary– “Ad hoc” meeting held at November 2003 Plenary– Gibson Ethernet Guitar demonstrated during 802 Orlando Social

Ethernet in the Consumer Ethernet in the Consumer MarketplaceMarketplace

7July 2004

““Consumer Ethernet”Consumer Ethernet”

• It’s already here– SOHO networking equipment

• Switches• Router/Firewalls• WLAN access points• Combo units – all of the above

• It’s sold in retail outlets in bubble pack– Computer stores– Electronic stores– Even DIY stores!

• It’s inexpensive• It’s high performance• It’s getting easier for non-technical end users to setup


8July 2004

Consumer MarketplaceConsumer Marketplace

• It’s huge!– Market for all consumer electronics ($96 B 2003)

• Pace of new product introduction is rapid– Product cycles are ~ 3-6 months (sometimes less)– Rapid change in features and performance

• Products are mass produced with tremendous economies of scale

• Enormous market pressure for low-cost high-performance exciting products


9July 2004

Why now?Why now?

– Several companies have home A/V equipment with Ethernet ports now, more to follow

– Digital media is the norm for home and professional A/V

• DVD for videos• CD, SACD, DVD-Audio for audio• Digital cable, digital satellite, High Definition TV

– Convergence:• It’s not just a buzzword, it’s really happening• Computers are used to play videos and music• “Consumer media servers” with hard drive recorders

– Increased penetration residential broad band access


10July 2004

Home Physical Infrastructure Home Physical Infrastructure

• New homes are now being wired with UTP cable

• According to the Consumer Electronics Association, 52% of new homes in the U.S. are constructed with structured wiring plants

• ISO/IEC has just approved the standard for residential structured wiring plants (SC25/WG3)


11July 2004

It’s already happeningIt’s already happening

Digital Living Network Alliance (DLNA, was DHWG) is already developing higher-level protocols that use Ethernet as the physical layer– Professional audio has used several proprietary

solutions for almost a decade• It’s very popular, but the solutions are proprietary (non-

standard)

– Professional video is looking for similar solutions– Using Ethernet will standardize the interface across

computers and A/V equipment


12July 2004

In SummaryIn Summary

– The home networking market has already chosen Ethernet for data

• The “home” part of SOHO is growing rapidly each year• There are already products on the market from several manufacturers-

--and there are more to come– The home audio/video industry is now deliberating about whether

to choose Ethernet– The expansion of Ethernet into audio/video will potentially create a

new market segment• Tens of millions of new Ethernet ports per year

– With increased broad band penetration and the completion of EFM, the home is the next Ethernet challenge for A/V apps

A/V Has Time Sensitive ApplicationsA/V Has Time Sensitive Applications

• Multi-Room Synchronization– Audio playback synchronized across multiple rooms– Video playback synchronized across multiple rooms and

maintaining lip-sync• Network Trickplay

– Multiple HDTVs accessing recorded shows on a Digital Video Recorder

– Each TV attempts slow/fast playback at same time

• Jam Session– Multiple instruments with live effects and mixing– Turn on instruments and immediately begin playing– 500uSec max latency, zero long term jitter

• Gibson Guitar experience at 100Mbps

Home Audio Use Case IHome Audio Use Case I

• User stores all his music files on a Network Attached Storage (Media Server) box connected via an Ethernet switch

• Each room has a digital audio receiver, connected to Ethernet, which can access and play any song from the Media Server– Digital audio receivers drive local speakers over ordinary speaker

wire

Home Audio Use Case IIHome Audio Use Case II

• Sometimes, the user wants one digital audio receiver to be the “master” and control what songs are played in other rooms through “slave” receivers– A single song in the whole house– A single song in selected rooms; e.g. living room, dining

room, and study, but not bedroom• Simultaneous audio playing in multiple rooms requires

synchronization and phase control of audio within the limits of human hearing to prevent “reverberation” throughout the house


20July 2004

Time Sensitive RequirementsTime Sensitive Requirements

• Precise End-Point Synchronization– Data/time synchronization must be sufficiently precise at little or no

cost– Ethernet today does not provide data/time synchronization

• Bounded Jitter and Latency– Bounded jitter and latency per A/V application is required

• Bandwidth Allocation Guarantee– Guaranteed protection from interfering streams is required

• Plus All the Existing Benefits of Ethernet– e.g. minimum packet loss

SummarySummary


39July 2004

• 802.3 was created to transport data applications• New Consumer Electronics apps place additional

quality requirements on Ethernet in the home– Require real application quality of service – Guaranteed network access– Plug and play with reliability for QoE– No “HELP” line for on-site fault services

• New apps bring new network timing requirements– Latency – Jitter– Differential delay

In Our 32th Year


40July 2004

In SummaryIn Summary

• The home brings new challenges for Ethernet as the “Converged” transport for PC’s & Audio/Video

• High quality and low cost are mandatory• Many other organizations now focused on home

– DLNA, CEA, UPnP, ITU-T, ETSI, and more

• Residential Ethernet should also provide a backbone for 802.11 and 1394

• Proprietary solutions exist and their number will expand unless IEEE802.3 addresses these issues
